Path of the Teapot

This is the family friendly version. Of course, you could also make things other than tea the center of the class.

The Path of the Teapot is followed by those rare warriors who believe rage should steep like a good brew: patiently, with purpose, and possibly with a hint of lavender. These barbarians carry enchanted teapots, sip their way through combat, and channel their boiling emotions into explosive displays of strength—often between sips of jasmine.

Level 3: Tea Addiction

When you choose this path at 3rd level, a teapot appears in your posession. You can speak to small and tiny objects and get proficiency with Tinker's tools.
In combat, you automatically enter a rage at the start of your turn (expending a use of Rage) unless you use a bonus action to sip tea and suppress it. If you're already raging, sipping tea as a bonus action ends your rage and heals you for 1d12 + your Constitution modifier. You must have a free hand to drink.

Level 6: Delicious Bribe

Starting at level 6, as an action, you can offer tea to a creature within 5 feet that can drink. If it’s willing or fails a contested Insight vs. your Persuasion, it accepts and is charmed by you for 1 hour, or until you or your allies act hostile toward it. You can use this feature twice per long rest.

Level 10: Boiling Rage

Upon reaching 10th level: Each time you suppress your rage by drinking tea (bonus action), you gain 1 Boiling Point (max 3). Each point lowers your Wisdom score by 1. When you next rage, you can expend all Boiling Points to gain that number as a bonus to attack and damage rolls for the rage’s duration. You can’t gain Boiling Points if you have no uses of Rage remaining.

Level 14: Insatiable Urge

Reaching 14th level, your dependence on tea has grown into an unquenchable thirst that shapes your very being. After a long rest, if you do not drink tea from your teapot before you begin the day,  you gain 2 Boiling Points. Your maximum Boiling Points increases to 5.
